El origen histopatológico de las lesiones es variable, pero la conducta local de las mismas suele ser agresiva, no correspondiendo en muchas ocasiones a su «benigna» apariencia histológica. Para llegar a un diagnóstico correcto es importante conocer características clínicas y de imagen que presenta cada lesión, realizar una adecuada toma de biopsia, además de contar con histopatólogos de experiencia en el reconocimiento de estos tumores, ya que de ello depende el correcto tratamiento a realizar. El objetivo del tratamiento es la resección de la lesión, restaurando función y estética facial y, de ser posible, favorecer el crecimiento de las estructuras anatómicas afectadas, siendo esto último difícil de llevar a cabo en hospitales del sector salud de presupuesto limitado, habiendo mucho por hacer en lo que se refiere a los tratamientos encaminados a favorecer el crecimiento óseo y posterior rehabilitación de las condiciones oclusales de los pacientes. En este artículo reportamos cuatro casos de tumores en pacientes pediátricos, de diferente estirpe histopatológica y de poca frecuencia, pero con la misma agresividad local, tratados en el Hospital de Alta Especialidad 134, del Instituto Mexicano del Seguro Social, Torreón, Coahuila, México.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Children rarely experience tumors in the face. Nevertheless, tissue damage caused by these tumors can modify facial growth and development causing physical, esthetic and psychological alterations. The histopathologiical origin of these lesions is variable, but their local behavior is frequently aggressive, oftentimes not matching their &#8220;benign&#8221; histological appearance. In order to reach accurate diagnosis it is important to be familiar with radiographic and clinical characteristics exhibited by all lesions, adequately take a biopsy, as well as count with histopathological operators with experience in the recognition of these tumors, since they ultimately are responsible for the treatment to be prescribed. Lesion resection is the treatment's objective, to restore facial esthetics and function, and, whenever possible, favor growth of any affected anatomical structures. This is not easy to achieve in government hospitals with limited resources. There is yet a lot to be achieved in the field of favoring bone growth and later rehabilitate patient's occlusal conditions. In the present article we present four cases of tumors in pediatric patients. Tumors were of different histopathological lineage and low frequency, but all were locally aggressive. These tumors were treated at the Hospital de Alta Especialidad 134, Mexican Institute of Social Security, Torreon, Coahuila, Mexico.]]></p></abstract>
